In a two slit experiment with monochromatic light, fringes

Last updated: 7/8/2022

In a two slit experiment with monochromatic light, fringes are obtained on a screen placed at some distance from the slits. If the screen is moved by a distance of 5 × 10-2 m towards the slits, the change in the fringe width is 3 × 10-² m. If the separation between the slits is 10-³ m, the wavelength of light used is A. 5 x 10^-7m B. 6 x 10^-7m C. 7 x 10^-7m D. 6 × 10^-6 m
